First in the Vespel ® family

of products— highly durable

polyimides that deliver

exceptional wear resistance,

insulation, and a low

coefficient of friction.

But, since we know you like

to push a little harder,

so did we. Within the S line,

Vespel ® Parts and Shapes

include many products with

differing sets of attributes.

So, you get exactly what

your design needs.

SP- 1 Need a material with superior wear and insulation properties? Semiconductor manufacturers often find our SP-1 products useful in their production processes. And, with operating temperatures from cryogenic to 300°C, great plasma resistance, plus a UL rating for minimal electrical and thermal conductivity, it isn’t hard to see why.

SP- 21 If insulation is less important than low-friction properties, then you’re looking for graphite-enhanced SP-21. Automotive engineers love to use SP-21 for parts like thrust washers, bearings and seals —because the low-friction properties mean they workwith or without lubrication.

SP- 211 Need a lower coefficient of friction than SP-21? Not as concerned about thermal and wear resistance? SP-211 could beyour solution. With Teflon® PTFE as an additive, the coefficient of friction is further reduced, even without lubrication.

SP- 214 If you need a material that can supply low-frictional properties and the benefits of even a longer life than our SP-21, lookto SP-214. It's an S-line solution designed to withstand some of your harshest conditions, in non-lubricated environments.

SP- 22 Designing with tight tolerances? SP-22 is the answer. When you’ve no room for error, SP-22’s minimal thermal expansionand dimensional stability give you the freedom to create exactly what you’ve imagined.

SP- 221 Created for highly specialized applications—against soft metals in “non-lube” conditions. Its excellent coefficient of fric-tion and good creep resistance mean that not only will your SP-221 part have excellent wear, but so will the soft metal parts thatcome in contact with it.

SP- 224 Need a bearing material that offers all the benefits of SP-22, plus the advantage of stable frictional properties and longerlife? SP-224 is your answer. This patented material goes the extra mile — providing additional load-carrying capability.

SP- 3 Of course, working in vacuum and dry environments has its own challenges. Aerospace engineers have to worry about extradifficulties like outgassing. But SP-3 has proven high performance in aerospace applications, largely due to its ultra-low outgassing.

SMR - 0454 & SMR - 0747 High modulus, low elongation, high compressive strengths and low creep—these products providethem all. Graphite-filled for low friction, SMR-0454 and SMR-0747 offer the same thermal resistance as the SP products, with less deflection under load. The addition of carbon fibers in SMR-0454 gives extra benefits: a steel-like coefficient of thermal expansion and better thermal conductivity.

ST- 2010 & ST- 2030 Want a material that wears like SP-21, but with improved toughness and better thermal oxidative stabil-ity? Consider ST-2010 or ST-2030. These products even include better resistance to solvents, acids and bases.

SCP- 5000 & SCP- 5 0094 Materials designed for those demanding applications that require even more toughness, thermal stability and chemical resistance than ST-2010. SCP-50094 has been put to the test in ultra-high-stress environments like aircraft engines.So, it’s ready for just about any design challenge. But for better plasma resistance, dimensional stability and chemical resistance than SP-1, check out SCP-5000.

SM - 30084 As any engineer knows, sometimes strength lies in flexibility. Allow us to introduce SM-30084. It was originally developed to provide higher elongation for engine piston rings and valve spring washers. But, because of its outstanding strength, SM-30084 is being tested more and more, showing truly incredible versatility.

SMP- 40025 S Line’s “best in class” regarding thermal oxidation resistance and thermal stability. (It’s even better than SCP-50094!) As such, SMP-40025 is ideal for use in jet engines—particularly high-vibration applications. Its high modulus and low elon-gation provide dimensional stability at temperatures and loads that make other polymers wilt.

SF- 0920 Other materials “can’t touch” SF-0920’s superior thermal and electrical insulating properties, not to mention resilient cushioning. That’s what sets SF-0920 apart from the rest of the Vespel® Parts and Shapes S line. This unique polyimide foam hashigh durability and thermal resistance that make it ideal for use in those “can’t-touch” hot-material-handling applications. Plus, it’slightweight and safe —won’t burn, offgas, or release toxic fumes.

TOUGH, VERSATILE, DIVERSE.S HAS A SOLUTION FOR ALMOST ANY DESIGN CHALLENGE.

S family tech sheet 1/24/03 3:58 PM Page 1

Introducing the

newest member of

the Vespel ® family — TP.

This innovative

thermoplastic material

lets you improve

functionality in ways you

never thought possible.

In fact, just like the S line,

TP parts have superior

wear, chemical and

temperature resistance;

you can even use them

to replace metal and

ceramic parts. And also

like the S line, various TP

products have been

created to fit a variety

of design specs.

TP- 1012BK Gears that are quiet, flexible and strong. Bushings that can be UL-V0 rated for flame resistance. TP-1012BK gives you high-modulus parts with superior wear resistance in dry environments.Plus, they’re an excellent value.

TP- 2346 Not many flexible materials can hold up under heat, solvents and chemicals…especially in non-lubricated environments. But TP-2346 can, and on top of everything else, it has great wear resistance! Thattoughness makes it perfect for use in transmission shift pads, ATV thrust washers, clutch buttons and more.

TP- 2875 Outstanding fuel and solvent resistance and a low coefficient of friction—TP-2875 is ideal forgasoline and diesel fuel-pump parts, thrust washers, and other applications in lubricated environments.

TP- 8005 Translucent polyimide parts designed specifically for semiconductor and high-purity applications. Plasma etch chamber components made with Vespel® TP-8005 have excellent erosion resistance. Parts are either thermoformed or injection molded for excellent geometric versatility.

TP- 8311 Looking for temperature-resistant parts with excellent mechanical properties? Whether you’reworking on lubricated or non-lubricated applications, TP-8311 is the answer. It can be used in shift leverbushings and thrust washers, plus gasoline or diesel fuel-pump applications.

TP- 8541 When you need compressor valve poppets and vanes that can really take a beating, think ofTP-8541. It has excellent mechanical properties (especially impact resistance), plus excellent chemical resistance and a high heat-deflection temperature.

TP- 8549 TP-8549’s excellent physical properties make it a great product for applications like blowermotor bushings on business machines, scanner mirror bushings and more.

TP- 8556 Seal rings require excellent compliance, wear and mechanical properties. TP-8556 does it all,and is especially easy to assemble in difficult manufacturing situations.

STRENGTH OFTEN LIES IN FLEXIBILITY.THAT’S WHY WE CREATED TP.

Be prepared for the worst.

We’re talking about some

of the harshest chemicals

in industry today. Luckily,

being prepared simply

means thinking Vespel ® CR

when you’re designing

for a tough chemical

environment. Plus, CR can

provide ultra-high purity

for semiconductor

applications, high-creep

resistance for seals, even

easy machinability for

tight-tolerance parts

like ball-valve seats.

And of course, aside from

chemical resistance, CR

falls in line with the other

Vespel ® Parts and Shapes

families —with its high

resistance to conventional

wear and corrosion.

So, what could CR do

for your design process?

CR- 6100 A Teflon® PFA body, reinforced with high-tensile-strength carbon fiber — CR-6100 offers excellent chemical resistance while exhibiting superior resistance to creep — even up to 550˚F! It also provides excellent wear resistance and easy machinability for tight-tolerance applications. Add in a CTE lower than steel in the x-y plane (due to planar carbon-fiber reinforcement), and you have an ideal material for a variety of applications.

CR- 6200 Has the same resistance to creep and chemicals as CR-6100, but with a more random orientationof its fiber. Consequently, CR-6200 doesn’t exhibit the degree of x-y property orientation provided by CR-6100,but offers a balance of properties in the z and x-y directions instead.

CR- 6300 & CR- 6500 In some situations, the electrical conductivity of carbon fiber is a downright nuisance.That’s why the forward-thinking engineers at DuPont are developing CR-6300 and CR-6500— the glass- andquartz-fiber-reinforced versions of CR-6100. Coming soon.

STANDS UP TO YOUR TOUGHEST ACID TEST. NOT TO MENTION BASES, SOLVENTS AND OTHER CHEMICALS.

We know. For your

designs to be successful,

they have to do more than

work well. They have to

keep on working,

year after year, in some

environments. Wear and

impact resistance are key.

You want polyimide

tube clamps that can

replace cast aluminum

or titanium, slide blocks

that are stronger than

powder-filled compositions,

and wear strips that

are self-lubricating.

That’s why CP was created.

We have an array of fiber-

for a range of unique

design needs.

CP- 0301 Sheet-molded and reinforced polyimide resin. Since it’s lightweight yet tough, CP-0301 is idealto use instead of aluminum or titanium in parts like aircraft brackets, gearbox adapter covers and sealplates. Plus, with CP-0301 tube clamps, you can create clamping systems that are more fatigue-resistantthan those using die-cast aluminum.

CP- 0644 , CP- 0648 & CP- 0650 Washers that are lighter-weight than aluminum. Bushings that areideal for high-temperature, high-friction, highly oxidative environments. Even self-lubricating slide blocks.CP-0644, CP-0648 and CP-0650 are fiber-reinforced composite fabrics that are stronger than powder-filled compositions, making your designs more durable.

CP- 8000 , CP- 8001 & CP- 8002 With high temperature resistance, high oxidation resistance, andenough strength to eliminate the need for metal, CP-8000, CP-8001 and CP-8002 are ideal for bushings in gasturbine engine compressors, balls for self-aligning spherical bearing assemblies and more. That extraordinarystrength comes from fiber-reinforced polymer matrices—braided into a tube or rope for maximum toughness.

a solution to meet your

individual performance

and value demands.

ASB - 0664 , ASB - 0826 & ASB - 3000 Rod ends with ultra-high oxidation resistance. Self-lubricatingtrack rollers. Wear-resistant, self-aligning spherical bearings. These polymer- and metallic-supported composites stand up to the toughest of engineering challenges. What’s more, we can consider any assembly technique to fulfill your performance and cost-benefit requirements.

ASB - 5 000 SERIES There’s heat, and then there’s heat. The ASB-5000 family was created to withstand the kind of heat that melts glass. Our line of metal-supported composites should be first in mindwhen you need to design for intensely high-temperature environments. In such applications, ASB is superior to straight-metal parts, especially because of its self-lubricating properties.

ASB -7000 SERIES Sometimes you need a part to do double duty. This product combines the performance of non-polymeric materials with the excellent properties of our TP product line. Specifically,materials like steel or ceramic are insert-molded with our TP resin.

ASB - 8000 SERIES Our S family has unique properties, which solve many difficult problems. But occasionally, customers need more geometric flexibility than our S products can provide. ASB-8000 products are composed of S parts overmolded with other engineered polymers.

INTRODUCTION

Vespel® CP parts & shapes are a family of

fiber-reinforced polymers that exhibit excellent

strength to weight ratios. This family employs

a variety of forms of fiber reinforcements

singularly or in combination. The part geometry

and production volumes generally guide the

selection of the type of reinforcement from

woven fabric to chopped fiber. The selection of

the fiber material(s) (carbon, graphite, glass,

aramid) and the polymer matrix (polyimide,

phenolic, epoxy) is based upon the application's

operating conditions (thermal & mechanical).

Because of the wide selection of reinforcing

structures, fiber materials, and polymers, the

Vespel® CP family of parts and shapes offers the

designer a wide array of flexibility.

This information is offered without charge as part of the DuPont Company’s service to its customers, but DuPont cannot guarantee that favorable results will be obtained from the use of such data. It isintended for use by persons having technical skill, at their discretion and risk.

All of the property data discussed in this brochure are based upon laboratory tests and/or performance of Vespel® parts in specific applications. The maximum use temperature, PV limit and otherperformance parameters of virtually all engineering materials will vary somewhat from application to application, and between laboratory data and actual applications, depending upon a number of factors intrinsic to each application. Therefore, the only way to determine how Vespel® parts will perform in your application is to test them in your application.

DuPont warrants only that the material itself does not infringe the claims of any United States patent; but no license is implied nor is any further patent warranty made.

CAUTION: Do not use DuPont materials in medical applications involving permanent implantation in the human body or permanent contact with internal body fluids or tissues.

Do not use DuPont materials in medical applications involving brief or temporary implantation in the human body or contact with internal body fluids or tissues, unless the material has been provideddirectly from DuPont under a contract which expressly acknowledges the contemplated use.

DuPont makes no representation, promise, express warranty or implied warranty concerning the suitability of these materials for use in implantation in the human body or in contact with internal bodyfluids or tissues.

SHEET MOLDINGCOMPOUND SERIES

The sheet molding compoundseries of Vespel® CP parts

consist of long, chopped fibersheld in a variety of polymermatrices. The discontinuous

nature of the fibers allows thefibers to align with the

contours of the part, permittingthe molding of relativelycomplex shapes, while

providing the reinforcingstrength where needed within

the part. Superior strengthversus aluminum at less

weight, Vespel® CP frees thedesigner to explore ways to

improve efficiency by reducingcomponent weight and

reducing friction.

VESPEL— THE ADVANTAGE OF DUPONT FORWARD ENGINEERING

DuPont aims to extend the life and efficiency of chemical and

thermal processes by increasing their ability to withstand severe

operating environments. That’s why we’re committed to a systems

approach in advanced composite technology.

Vespel® CR parts are used in a wide range of chemical processing,

fluid power engineering and thermal management equipment

applications. They are ideally suited for valve seats and seals,

bearings and gaskets, plus pump and compressor components.

Plus, CR parts offer longer part life, reduced operating costs and

increased reliability.

WHAT IS VESPEL CR?

Chemical- and creep-resistant parts, created through DuPont

composites technology. Vespel® CR parts are based on a high-

performance Teflon® matrix, reinforced with high-aspect-ratio

(length/diameter) fibers. Even under adverse conditions, these

parts provide outstanding compressive creep resistance, high

toughness, dimensional stability at high temperatures and

pressures, and excellent chemical resistance. Vespel® CR can

improve the performance of your designs, with properties like

excellent chemical resistance, virtually no compressive creep,

dimensional stability across a wide temperature range, a high

degree of toughness, and superior wear characteristics.

CR Folder 6/3/03 12:11 PM Page 1

VESPEL CR’S BEST FEATURE — CHEMICAL RESISTANCEWhen parts are made from Vespel® CR, good chemical resistance is one of their best performance properties. It’s fairly typical of high-performancefluorinated polymers. But end-use behavior in specific conditions must alsobe taken into consideration. Variables like temperature, aeration, flow velocity, exposure duration, fluid stability and degree of contact help todetermine a part’s suitability in a particular situation.

In the Use Performance chart (upper right), results are listed for DuPont testsdone in various chemicals and under various conditions.

Our Chemical Resistance chart (lower right) demonstrates CR’s dimensional stability and strength in a separate set of tests performed usinga wider range of compounds and different conditions.

Component tests are ongoing, both for additional environments and end-useconditions, so look for updates periodically..CHEMICAL- AND CREEP- RESISTANT PARTS FOR IMPROVED PERFORMANCE IN SEVERE ENVIRONMENTSValve Components: Valve seats and packing backup made from Vespel® CR benefit from extra creep resistance and low frictional characteristics, especially at elevated temperatures.

Compressor Parts: Piston and rider rings benefit from the excellent wearand thermal properties of Vespel® CR’s composite structure.

Pump Components: Pump bearings, bushings and transmission componentstake advantage of the material’s dimensional stability, high PV rating and exceptional mechanical properties.

Compressor Parts: Valve plates made from Vespel® CR will benefit from thematerial’s impact resistance and toughness.

CR- 6100 A Teflon® PFA body, reinforced with high-tensile-strength carbon fiber — CR-6100 offers excellent chemical resistance while exhibiting superior resistance to creep — even up to 550˚F! It also provides excellent wear resistance and easy machinability for tight-tolerance applications. Add in a CTE lower than steel in the x-y plane (due to planar carbon-fiber reinforcement), and you have an ideal material for a variety of applications.

CR- 6200 Has the same resistance to creep and chemicals as CR-6100, but with a more random orientation of its fiber. Consequently, CR-6200 doesn’t exhibit the degree of x-y property orientation provided by CR-6100, but offers a balance of properties in the z and x-y directions instead.

CR- 6300 & CR- 6500 In some situations, the electrical conductivity of carbon fiber is a downright nuisance. That’s why the forward-thinking engineers at DuPont are developing CR-6300 and CR-6500—theglass- and quartz-fiber-reinforced versions of CR-6100. Coming soon.


Be prepared for the worst.

We’re talking about some

of the harshest chemicals

in the industry today.

Luckily, being prepared

simply means thinking

Vespel ® CR when

you’re designing

for a tough chemical

environment. Plus, CR can

provide ultra-high purity

for semiconductor

applications, high-creep

resistance for seals, even

easy machinability for

tight-tolerance parts

like ball-valve seats.

And of course, aside from

chemical resistance, CR

falls in line with the other

Vespel ® parts and shapes

families —with its high

resistance to convention-

al wear and corrosion.

So, what could CR do

for your design process?

RANDOMLY ORIENTEDFIBERS FOR CHEMICALLY

RESISTANT SHAPES

Vespel® CR-6200 is a carbonfiber-filled thermoplastic

fluoropolymer designed for use in hostile chemical

environments. Due to its lowcreep and high thermal

resistance, Vespel®

CR-6200 often excels whereother chemically resistantplastics fail. This makes

Vespel® CR-6200 particularlywell suited for seals, wear

rings and other componentsused in a variety of devicesand operating conditions.

The fiber reinforcement contained in CR-6200 has less

x-y plane orientation thanthe fibers of CR-6100.Consequently, CR-6200

mechanical strengths are generally lower than x-y

strengths of CR-6100, and theCR-6200 x-y and z-direction

strengths are more comparableto each other and are

superior to the z-directionproperties of CR-6100.

INTRODUCTION

Vespel® TP is a ThermoPlastic family of materials

developed by DuPont to further serve the diverse

needs of our customers and markets. DuPont

has been perfecting high-temperature, high-

performance engineering polymers since 1967.

And Vespel®TP is built on that experience, taking

part-geometry possibilities further, without

complicated new processing techniques. This

line of high-temperature and high-performance

thermoplastic materials allows parts to be

formed using typical melt-processing techniques

such as injection-molding, extrusion and

thermoforming. Vespel® TP parts are produced to

customer specifications by a global network of

DuPont-qualified manufacturing partners. Each

facility is ISO/QS9000 certified, giving our

customers assurance of part quality. And in its

never-ending quest for continuous improvement,

DuPont is exploring development of additional

grades to address future needs.

TP Folder 5/30/03 10:49 AM Page 1

BENEFITSThe Vespel® TP family is comprised of two material types. The 8000Series offers high heat and wear resistance, plus high strength. The1000, 2000 and 7000 Series, being semicrystalline in nature, offer highchemical resistance in addition to good heat and wear resistance.

Geometric Flexibility: These grades can be injection-molded, provid-ing engineers with unprecedented freedom to creatively solvedesign problems. Also, by molding net shape or near net shape parts, expensive and time-consuming secondary operations are eliminated.

Part Consolidation: Given the geometric flexibility that comes withthese products, multiple components can be incorporated into a singledesign, reducing tooling, inventory and part handling costs. Whenmetal or ceramic mating components are involved, insert-moldingVespel®TP is always an option — adding more design flexibility andoverall part functionality.

Weight Reduction: The high heat and wear performance of Vespel®TPmakes these materials ideal candidates for replacing metal components. In most cases, parts can be redesigned to allow material to be removed from the bulk of the part while retaining functional requirements. Combine less material with the lower specific gravity of Vespel® TP (versus metal), and you get a low-weight, high-performance part.

This information is offered without charge as part of the DuPont Company’s service to its customers, but DuPointended for use by persons having technical skill, at their discretion and risk.

All of the property data discussed in this brochure are based upon laboratory tests and/or performance of performance parameters of virtually all engineering materials will vary somewhat from application to applicfactors intrinsic to each application.

Introducing the

newest member of

the Vespel ® family—TP.

This innovative

thermoplastic material

lets you improve

functionality in ways you

never thought possible.

In fact, just like the S line,

TP parts have superior

wear, chemical and

temperature resistance;

you can even use them

to replace metal and

ceramic parts. And also

like the S line, various TP

products have been

created to fit a variety

of design specs.

VESPEL Territory . . . Performance Plus

IntroductionIf you need to insure the dependable performance ofparts critical to the successful operation of your design,you may be in Vespel Territory.

If you need to reduce warranty costs caused by thepremature failure of critical parts in an existing product,you may be in Vespel Territory.

If you need any combination of Low wear and friction at high pressures and

velocities, Outstanding creep resistance, Lubricated or unlubricated performance, Strength and impact resistance, or Continuous operation at 500°F with excursions

to 900°F

You’re in Vespel Territory.

Vespel parts, manufactured by DuPont to your designfrom high performance polyimide resin, provide a uniquecombination of the physical properties of plastics, metalsand ceramics. Vespel parts offer you design flexibility.Often several parts can be combined into one, partscan be designed to simplify product assembly, or partscan be eliminated. As with metals and ceramics, Vespelparts can successfully perform in demanding physicalenvironments.

The property data which follows, except where noted,are the result of extensive testing of parts machinedfrom SP polyimide shapes. If your need involves the

production of more than 1,000 parts a year you shouldconsider direct-formed Vespel parts, normally the mostcost-effective way to produce parts for high-volumeapplications. Contact your local DuPont Vespel Market-ing Representative before you begin your design. He willbe happy to provide information on direct-formed SPparts, to discuss similar applications and to help youobtain Vespel materials for testing and prototyping.

Direct-formed SP parts are produced with the pressureapplied unidirectionally, resulting in some anisotropy, ordirectionality, of properties. Directionality is increasedwith the addition of fillers. The highest strength andelongation and the lowest thermal expansion are foundin the direction perpendicular to the pressing direction inmost parts. The data presented here for direct-formedparts, except for compressive properties and thermalconductivity, were obtained in the perpendicular direction.The typical properties of machined parts were obtainedfrom samples prepared from isotropic material. Thematerial is formed so that properties are uniform through-out regardless of direction.

Take a moment to explore the boundaries of VespelTerritory. See for yourself the superior performance youcan obtain by designing with DuPont Vespel parts.

†† Unlubricated in air (PV-.875 MPa m/s)).

** Steady state, unlubricated in air.

Stress-Strain CurvesFigures 1 and 2 show typical stress-strain curves intension for machined SP polyimide parts at 73°F(296°K) and 500°F (533°K); Figures 3 and 4 showsimilar curves for direct-formed parts. The curves fora given composition differ between the two formsbecause of the lower density of the direct-formed parts.

Figures 5 through 7 provide data on stress-strain incompression. While you can load most SP polyimidecompositions in compression to high strains (>30%)without reaching ultimate strength, in practice this wouldresult in a grossly deformed part. The curves showinglow strains (up to 5%) illustrate the practical limits ofloading without significantly exceeding the elastic limitsof the materials. Table 1 provides the compressivestress data circulated for 0.1% permanent deformationin the part. Unlike thermosetting materials, SP polyimidecan be compressed several percent before reaching thisdeformation level. The materials are quite compliant anduseful in forming seals of many types.

9

Effect of TemperatureSince SP polyimide does not melt and has no glasstransition temperature (Tg) or softening point as mea-sured by the usual methods, strength and moduli de-crease with temperature in a nearly linear manner. Thiscontrasts to the usual engineering thermoplastic whichshows a large decrease in these properties as the Tgis approached. Figures 8 through 11 illustrate typicalchanges in tensile strength and modulus of elasticitywith temperature for machined and direct-formed parts.

The upper use temperature of SP polyimide is limited byits rate of degradation, not by a softening point where itwould lose its load-carrying capability. Parts may be usedcontinuously in air at 500°F (533°K) and for short excur-sions to as high as 900°F (755°K).

1

Figure 12 illustrates usefulness at high temperatures interms of time to 50% reduction in initial tensile strength.For example, after 100 hours continuous exposure to airat 700°F (644°K), SP-1 polyimide will retain half its initialstrength. The graphite filler in SP-21 and SP-22 polyi-mide imparts some physical stability to the parts which ismanifested in a greater retention of properties with time.SP-21 (15% graphite) requires about 200 hours at 700°F(644°K) and SP-22 (40% graphite) 350 hours to reachthe 50% strength level. The loss in properties with timeat temperatures up to about 750°F (672°K) is due almostentirely to oxidative degradation. At temperatures up toat least 650°F (588°K), SP parts will perform in inertenvironments such as nitrogen or vacuum with negligibleloss of properties with time.

11

Creep and Stress RelaxationThe time-dependent deformation which occurs in aplastic material under constant stress is called creep.

Creep at a given time is the difference between the totalstrain at that time and the initial instantaneous strainexperienced on loading.

The time-dependent decrease in the stress needed tomaintain a constant strain is called stress relaxation.

Figures 13, 14 and 15 show total deformation or strainvs. time under 1500 and 2500 psi (10.3 and 17.2 MPa)for machined SP-1, SP-21 and SP-22 polyimide at twotemperatures.

Since SP polyimide doesn’t soften and is thermallyresistant, it can carry loads at temperatures beyond thereach of most plastic materials and do so while exhibitingextremely low creep. Creep resistance is further en-hanced in the graphite-filled compositions, SP-21 andSP-22. For example, Figure 15 shows that creep forSP-22 polyimide at 2500 psi and 572°F is only 0.5%after 1,000 hours.

12

13

Figures 16 through 18 give the change in apparentmodulus of elasticity with time corresponding to Figures13 through 15. Substituting the appropriate time-dependent apparent modulus for elastic modulus instandard engineering equations will allow predictionof the effects of creep and stress relaxation.

14

15

Effect of Moisture AbsorptionFigures 19 through 21 illustrate typical rates of dimen-sional change caused by moisture absorption for ma-chined and direct-formed parts made of SP polyimide.Time to reach equilibrium moisture content from the drystate in a controlled environment is very long, involvingthousands of hours. Since the absorption of moisture isdiffusion controlled, the rate is inversely affected by theminimum dimension of the part.

Figures 22 and 23 show typical effects of relative humid-ity (RH) changes at 73°F (296°K) on the dimensions ofmachined and direct-formed parts. A part attains its fulldimensional change at a given humidity level only afterit has reached equilibrium in the particular environment.Allowing a completely dry part to reach equilibrium at100% RH at 73°F (296°K) will result in a maximumchange of about 0.5% or .005 in/in (mm/mm).

Thermal ExpansionLinear dimensional change with temperature is shown inFigure 24 for machined SP polyimide and in Figure 25 fordirect-formed polyimide. Each plot contains the averagecoefficient of thermal expansion over the temperaturerange 73°–572°F (296°–573°K) in both British and SIunits. The coefficient over any other range of temperaturemay be slightly different and can be determined from thecurves by dividing the percent dimensional change overthe desired range by 100 × the temperature differentialin degrees (∆T).

For all compositions, thermal expansion of direct-formedparts is lower than for machined parts—a result of the“directionality” of direct-formed parts, as discussedearlier.

The addition of graphite filler reduces thermal expansion.Thus, SP-21 and SP-22 polyimide offer a lower expan-sion than unfilled SP-1. The coefficient of thermal expan-sion of SP-22 approaches that of aluminum.

Fatigue and Impact ResistanceFailure of materials at stress levels lower than theirultimate tensile strengths when the applied stress isrepeated cyclically is known as fatigue failure. A plot ofstress to cause failure at 105 to 107 cycles vs. tempera-ture to 500°F (533°K) is shown in Figure 26 for machinedSP-1 and SP-21. Stress was applied by alternatingtension and compression at 1800 cycles per minute.At this frequency there is little or no effect of overheatingof the specimen which could cause premature failure.

Although fatigue data obtained through testing proce-dures can be used as a guide in designing parts, theyshould not be used without considering environment andstress concentrations. While test specimens usually havesmooth surfaces, the presence of notches, scratches,holes or sharp corners can cause concentration of stress.No fatigue tasting is a substitute for actual or simulatedend-use testing of a part.

Impact resistance is difficult to predict since the geometryof the part, stress concentrations and the rate of loadingall have an effect. To increase impact resistance, partsshould be designed to obtain the maximum area of loadapplication. Designing a part for maximum flexibility willalso help by increasing the distance over which impactenergy is expended.

SP polyimide, like most other plastics, displays notchsensitivity as shown by the values of notched Izod impactstrength shown in Table 1 (page 4). As with most materi-als, avoid designing sharp corners and other stressraisers into the part.

Chemical EffectsVespel SP parts perform well in a variety of chemicalenvironments. The tensile strength data shown in Table 3were determined using exposure tests patterned afterASTM Method D543-67, “Resistance of Plastics toChemical Reagents.”

Organic SolventsIn general, exposure to solvents for prolonged periods overa wide temperature range does not affect the mechanicaland dimensional properties of Vespel parts. Chlorinatedand fluorinated solvents such as FREON fluorocarbon,can be used for surface cleaning of Vespel parts as longas adequate ventilation exists.

At elevated temperatures some hydrocarbon solventscontaining functional groups, such as M-cresol andnitrobenzene, can cause SP polyimide parts to swell;however, Vespel parts are suggested for service in avariety of industrial fluids (fuels, oils, lubricants) at elevatedtemperatures. Generally, Vespel parts exposed to thefluids detailed in Table 3 exhibit no significant change indimensions or mechanical properties. However, the compo-sitions of industrial fluids differ among manufacturers andcan vary over time with any single manufacturer. Testingis recommended for each proposed use of Vespel parts toprovide quantitative guidance on the effect of the specificenvironment.

Aqueous MediaSP polyimide parts can be exposed to water up to 212°F(373°K), provided the stresses are low enough to take intoaccount the reduced mechanical properties. At 212°F(373°K), the tensile strength and elongation of SP poly-imide parts are reduced to 45% and 30% of the originalvalues, respectively, in about 500 hours, at which pointthey level out. Some of the reduced tensile propertiescaused by moisture absorption may be restored by drying.

(1) Swelling.

(2) SP-21 polyimide (15% graphite-filled).

As with all polyimides, SP polyimide resin is subject tohydrolysis. Cracking may occur on prolonged exposureto water or steam at temperatures exceeding 212°F(373°K). Actual end-use testing should be conducted forapplications involving such exposure.

Aqueous salt solutions will have the same effect on SPpolyimide parts as water.

BasesSP polyimide parts are susceptible to alkaline attack,which leads to a loss of mechanical properties. Exposureto ammonia and hydrazines (anhydrous liquids or vapor),primary and secondary amines, and solutions having apH of 10 or more must be avoided.

Oxidizing AgentsChemical reagents which act as powerful oxidizingagents (i.e., nitric acid, nitrogen tetroxide, etc.) can causeoxidation of Vespel parts. Weaker agents will requireend-use testing.

Oxygen CompatibilitySP-21 (15% graphite-filled) is compatible with liquid andgaseous oxygen systems. The National Aeronautics andSpace Administration tested the material, which meetsMSFC-SPEC-106B, “Testing Compatibility of Materialsfor Liquid Oxygen Systems”. At the present time thisapproval is on a selected-lot basis.

Similarly, SP-21 was tested by the Naval Air EngineeringCenter, U.S. Navy, and was found compatible accordingto MIL-V-5027C, “Non-Metallic Materials Compatible withOxygen.”

Other filled SP polyimide compositions should also meetthese specifications but none have been tested to date.The unfilled resin, SP-1, does not meet these standards.

Electrical PropertiesThe combination of good electrical properties, highstrength, and excellent thermal and radiation resistancemakes unfilled Vespel parts outstanding candidates forelectrical applications in severe environments. Moreimportantly, Vespel parts retain their electrical propertiesat high temperatures.

Figure 27 shows a decreasing dielectric constant forSP-1 polyimide with temperature at frequencies from 102

to 105 Hz. The change reflects a reduction of absorbedmoisture with increasing temperature. Dried specimenshave a dielectric constant of 3–3.1 over the temperaturerange. Likewise, the dissipation factor (Figure 28) of adried specimen is about .001 at the lower temperatures.Moisture content has relatively little effect of resistivity.

Volume and surface resistivities of SP-1 decreasewith increasing temperature (Figures 29 and 30). Thegraphite-filled compositions are not recommended forelectrical applications although high resistivity valueshave been obtained with parts produced from them. Ifgraphite is exposed on the surface of the parts as formedor machined, resistivity can decrease quite dramatically.

Figures 31 and 32 show the dielectric strength of ma-chined SP-1 as a function of air temperature and samplethickness.

The corona resistance of SP-1 is superior to that offluorocarbons and polyethylenes. For example, at200 v/mil (60 Hz and room temperature), corona lifeis 2200 hours.

Other PropertiesWeatheringSP polyimide parts undergo some loss of tensile strengthand elongation after prolonged outdoor exposure andshould be considered for such applications only aftersuitable testing. Vespel parts are completely resistantto fungus attack and test specimens have met therequirements of MIL.E 5272 and of federal specificationCCC-T-191 b, Methods 5762 and 5751, for resistanceto mildew and rot.

Radiation ResistanceVespel parts have outstanding resistance to high energy,ionizing radiation. A test sample prepared from unfilledSP polyimide, irradiated in a 2MEV Van de Graff beam atan intensity of 10 watts/cm2 (absorbed dose of 4 x 109

rads), showed no significant change in tensile strength,elongation or appearance. After 1500 hours in theBrookhaven Pile at 175°C (488°K), giving an absorbeddose of about 1011 rads, the SP polyimide sample wasembrittled but still form-stable.

Toxicological AspectsNo toxicological effects attributable to SP polyimidewere found in laboratory animals exposed to the resinby inhalation, ingestion or skin application. Applicationhas not been made for approval by the Food and DrugAdministration for use of Vespel parts in contact withfood products.

SP polymer is extremely heat-stable compared to mostorganic materials but can yield carbon monoxide (CO) asa product of combustion. To make sure the CO concen-trations remain below the acceptable safe level, careshould be taken to provide adequate ventilation whereVespel parts are exposed to elevated temperatures inconfined locations.

OutgassingOnce absorbed moisture has been removed from Vespelparts, weight loss in vacuum at high temperatures islow. In tests run by NASA at the Lewis Research Center,samples first dried at 200°F (366°K) gave a weight lossrate of less than 10–10 grams/cm2/sec. at temperaturesbelow 500°F. At 600°–700°F (500°–644°K) the weightloss rate was 10–7 grams/cm2/sec.
